Full textNanostructures are physical systems of paramount interest for both fundamental studies and applications, since they display quantum effects such as confinement, energy discretization, coherence…The quantum behavior of nano-devices can however be strongly influenced by disorder, thermal and non-equilibrium effects. In this Thesis, we show, for instance, how dissipation deeply affects the electron transport in superconducting nano-devices at microwave frequencies.By using a home-made cryogenic AFM/STM setup, we are able to investigate different kinds of nanostructures. First, we address the realization of a Single Electron Transistor with a Scanning Probe. Metallic nanoparticles are well known for their behavior as 0D-Quantum Dots (QD), and they display quantum confinement and charging effects, which are evidenced in our low-temperature SPM measurements as well. We demonstrate how a novel nanofabrication process can be implemented with the addition of gate electrodes sufficiently thin and leakage-proof, which in the future can provide a fine-tuning of the QD's properties and allow spatially-resolved exploration of quantum phenomena in a variety of different coupling regimes. Second, we study epitaxial graphene on SiC as a very promising 2D material for electronics. In particular, epitaxial sidewalls graphene nanoribbons (GNRs) are nanostructures of fundamental interest which can provide direct and controllable access to charge neutral graphene. Due to quantum confinement, these systems can display exceptional ballistic transport at room temperature. We implemented an innovative Scanning Tunneling Potentiometry technique allowing for nm-scale spatial resolution and μ V-scale voltage resolution. Measured local potential and resistance of single GNRs devices provide clear indication of non-diffusive transport.The physics investigated and the methods and the techniques developed in this Thesis can thus provide a new insight on several (and quite diverse) on-trend topics

Full textThis study concerns the nonlinear (NL) optical characterization mainly of order 3 in the visible, UV and IR in the picosecond regime of different materials such as solvents, lithium niobate and graphene nanosheets. We first present the expressions of NL susceptibilities. We then describe the Z-scan characterization technique and its variants. We present a new method that combines the advantages of Z-scan with those of dark field microscopy. We show that this imaging technique, called DFZ-scan (Dark Field Z-scan), can measure NL refractive coefficients in the presence of high NL absorption. The experimental results show a significant improvement in the sensitivity. Finally, we compare the NL responses of the most commonly used solvents, including water with the lowest NL refraction. This liquid is used to characterize the NL response of a suspension of graphene quantum dots. Using a simple model, we estimate the refractive index and absorption index NL of a single-layer graphene nanosheet. We also studied higher order non-linearities in liquid (toluene) and solid (LiNbO3) materials for potential applications in second harmonic generation and waveguide modulators. These coefficients can be of interest to a large community of researchers in fields as diverse as filamentation, soliton, all-optical signal processing and telecommunications networks
